This provides DT binding documentation, device driver, documentation and MAINTAINER files. A visconti VIIF driver instance exposes 1 media control device file and 3 video device files for a VIIF hardware. Detailed HW/SW are described in documentation directory. The VIIF hardware has CSI2 receiver, image signal processor and DMAC inside. The subdevice for image signal processor provides vendor specific V4L2 controls. The device driver depends on two other drivers under development; clock framework driver and IOMMU driver. Corresponding features will be added later. Best regards, Yuji Changelog v2: - Resend v1 because a patch exceeds size limit. Changelog v3: - Add documentation to describe SW and HW - Adapted to media control framework - Introduced ISP subdevice, capture device - Remove private IOCTLs and add vendor specific V4L2 controls - Change function name avoiding camelcase and uppercase letters [0]: https://toshiba.semicon-storage.com/ap-en/semiconductor/product/image-recognition-processors-visconti.html Yuji Ishikawa (4): dt-bindings: media: platform: visconti: Add Toshiba Visconti Video Input Interface bindings media: platform: visconti: Add Toshiba Visconti Video Input Interface driver documentation: media: add documentation for Toshiba Visconti Video Input Interface driver MAINTAINERS: Add entries for Toshiba Visconti Video Input Interface .../bindings/media/toshiba,visconti-viif.yaml | 103 + .../driver-api/media/drivers/index.rst | 1 + .../media/drivers/visconti-viif.rst | 455 +++ MAINTAINERS | 3 + drivers/media/platform/Kconfig | 2 + drivers/media/platform/Makefile | 4 + drivers/media/platform/visconti/Kconfig | 9 + drivers/media/platform/visconti/Makefile | 9 + drivers/media/platform/visconti/hwd_viif.c | 1791 +++++++++++ drivers/media/platform/visconti/hwd_viif.h | 701 +++++ .../media/platform/visconti/hwd_viif_csi2rx.c | 723 +++++ .../platform/visconti/hwd_viif_internal.h | 348 ++ .../media/platform/visconti/hwd_viif_l1isp.c | 2727 ++++++++++++++++ .../media/platform/visconti/hwd_viif_reg.h | 2802 +++++++++++++++++ drivers/media/platform/visconti/viif.c | 479 +++ drivers/media/platform/visconti/viif.h | 195 ++ .../media/platform/visconti/viif_capture.c | 1215 +++++++ .../media/platform/visconti/viif_controls.c | 1149 +++++++ drivers/media/platform/visconti/viif_isp.c | 852 +++++ include/uapi/linux/visconti_viif.h | 1724 ++++++++++ 20 files changed, 15292 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/toshiba,visconti-viif.yaml create mode 100644 Documentation/driver-api/media/drivers/visconti-viif.rst create mode 100644 drivers/media/platform/visconti/Kconfig create mode 100644 drivers/media/platform/visconti/Makefile create mode 100644 drivers/media/platform/visconti/hwd_viif.c create mode 100644 drivers/media/platform/visconti/hwd_viif.h create mode 100644 drivers/media/platform/visconti/hwd_viif_csi2rx.c create mode 100644 drivers/media/platform/visconti/hwd_viif_internal.h create mode 100644 drivers/media/platform/visconti/hwd_viif_l1isp.c create mode 100644 drivers/media/platform/visconti/hwd_viif_reg.h create mode 100644 drivers/media/platform/visconti/viif.c create mode 100644 drivers/media/platform/visconti/viif.h create mode 100644 drivers/media/platform/visconti/viif_capture.c create mode 100644 drivers/media/platform/visconti/viif_controls.c create mode 100644 drivers/media/platform/visconti/viif_isp.c create mode 100644 include/uapi/linux/visconti_viif.h
